English title: Studies on the effect of weather conditions on diameter and height growth of Scots pineAbstract
The height and diameter growth measured from different Scots pine (Pinus sylvestris L.) stands in Southern Finland was compared with meteorological information. The height growth benefits from warm weather in late summer in the previous year, and especially from high temperatures in June. Precipitation or the temperature in the same year did not affect the height growth. Diameter growth benefits from high temperatures in the spring of the same year, especially in April. High precipitation in the spring has in some cases negative impact on the diameter growth. The different combinations of precipitation and temperature can have variable effects on tree growth. In the diameter growth was seen a periodicity that coincides with sunspots.
